Answer
# 1
8085 microprocessor has a set 5 flip flops which serves as
the status flags & they are : Sign Flag ,Carry Flag,
Auxillary Carry Flag, Parity Flag & Zero Flag

Answer
# 3
zero flag:if result is 0 than it is set condition i.e.1
otherwise it is reset i.e.is 0.
carry flag:if an extra bit arises than it is set condition
i.e.1 otherwise it is reset i.e.is 0.
sign flag:in it only D7 is considered.if D7 is 1 than it
is set condition i.e.1 but if D7 is 0 than it is reset
i.e.is 0.
parity flag:if number of 1's in the answer is even than it
is set condition i.e.1 otherwise it is reset i.e.is 0.
auxilary carry flag:if a carry is generated in D3 & passed
to D4 than ac flag is set condition i.e.1 otherwise it is
reset i.e.is 0.

Answer
# 4
there r 5 different types of flags r there.
that is
Sign Flag ,Carry Flag, Auxillary Carry Flag, Parity
Flag & Zero Flag

Ex:
Sign Flag: when the out will come to all zeros that time
zero flag will set.

carrr flag:
the carry flag the more then the eight bits adding
or some other things that carry will come that time the
carry flag will set...

Answer
# 7
there are five flip-flop in 8085 which individually denote the characteristic if the ALU result.
1.Sign flag(S): S=1, if D7=1; otherwise S=0;
2.Zero flag(Z): Z=1,if A=00H; otherwise Z=0;
3.Auxiliary flag(AC): AC=1, if a carry is generated from the addition of fourth bit from right of a 8-bit binary no. otherwise AC=0;
4.Parity flag(P): P=1, if A has even parity;
P=0, if A has odd parity;
5.Carry flag(CY): CY=1,Carry is generated;
CY=0,Carry is not generated;

Answer
# 8
in microprocessor 8085 hav 5 flag register
1.zero flag-if the result is zero then it is set to 1 oter
wise 0
2.parity flag-if in the answer num of 1's is even then then
it set to 1 otherwise 0
3.sign flag
4.auxillury flag-
5.carry flag-if carry is arises then it set to 1 oterwise 0

Answer
# 9
Carry Flag (CF):- When two 8/16 bit number addition the the
result is generate 9/17 bit number then the carry flag is set.

Auxiliary flag (AF):-This flag is active in BCD number.When
Two 8 bit number addition the the carry is generate by D3
bit to D4 bit the the Auxiliary flag is set.

Parity Flag (PF):-This flag is indicate the number is even
or odd.The numbers of one's in result is even 0,2,4,6,8 then
parity flag is set and the number os one's is odd 1,3,5,7
the the parity flag is reset.

Zero Flag (ZF):-This flag is indicate the result is zero or
non-zero.when two 8 bit number addition then the result is
zero then zero flag is set.and the result is non-zero then
the zero flag is reset.

Sign Flag (SF):-This flag is indicate the number is negative
or positive.The MSB in result is one(1)then the sign flag is
set or the result is negative And the MSB in result in
Zero(0) then the sign flag is reset or the result is positive.
